Title: Gas turbine combustor
Inventor: SAITO TSUKASA
IPC: F23R3/32
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To provide a gas turbine combustor capable of executing stabilized combustion for a wide area without providing a pilot burner separately even in an attempt to reduce nitrogen oxide on a pre-evaporation and pre-mixing combustion method. SOLUTION: A swirler 24, which serves as a swirling blade, is provided at a connecting area 23 with a combustor 21 at the tip of a pre-evaporation and a pre-mixing pipe 22. This swirled 24 exerts a centrifugal force on the flow of a combustion gas so that a gas area at a slow flow rate may be produced at the central part of the flow of combustion gas, which makes to possible to stop the spread of flames near the tip of the pre-evaporation and pre-mixing pipe 22 and continues stabilized combustion in a wide area (the change area of a gas turbine or the change area of fuel gas supply) without providing a pilot burner separately. It is, therefore, possible to contrive to reduce nitrogen oxide all the more for the elimination of nitrogen oxide from the pilot burner.
